Description Frank DENIS 2008-03-03 23:00:03 UTC 
ports/lang/neko perfectly works on FreeBSD 7.0 as long as there is only one
core.

On a SMP system, it crashes with a corrupted stack as soon as it tries to
create a thread.

The behavior can be reproduced with vmware.

Fix: 

Don't know.
Maybe boehm-gc releated.
How-To-Repeat: - Install neko from ports
- Download ftp://ftp.c9x.org/misc/server.n
- Run neko server.n 0.0.0.0 1935
- Try curl -v http://127.0.0.1:1935
- crash on SMP, ok on UP.
Comment 1 Frank DENIS 2008-03-04 23:17:03 UTC 
The Neko virtual machine is indeed broken on FreeBSD 7 + SMP.

Here's a very simple way to make it crash. Just create a thread.

$ echo '$loader.loadprim("std@thread_create", 2)(function(z)  
{ $print(z) }, "OK");' > nekothread.neko

$ nekoc nekothread.neko

$ neko nekothread.n

lang/neko is not longer in the freebsd ports tree.
